Fig. 1 is a structural representation of the present invention.
Fig. 2 is a decomposing schematic representation of the present invention.
Fig. 3 is a functional-block diagram of the present invention.
Embodiment:
Below in conjunction with accompanying drawing the present invention is further described; See shown in Fig. 1~3; Automatically adjustment brightness and photochromic illuminating lamp include lamp body 1, and lamp body 1 is provided with sensing module 2, scalable brightness and photochromic led light source 3, driving power 4; Sensing module 2 includes the light sensor 22 of sensing control circuit 21, sense ambient light line strength, the temperature sensor 23 of sense ambient temperature; The input of driving power 4 connects the output of sensing control circuit 21, and the output of driving power 4 connects led light source 3, and light sensor 22 and temperature sensor 23 are connected the input of sensing control circuit 21 respectively.Light sensor 22 is a photodiode, and temperature sensor 23 is temp probe, and highly sensitive, sensing is accurate.
Illuminating lamp of the present invention is a Grille lamp, and lamp body 1 includes reflection shield 11, is installed at least one heat dissipating housing 12 of reflection shield 11 rear ends, is provided with LED lamp plate 5 in the heat dissipating housing 12; LED lamp plate 5 the place aheads are provided with diffuser plate 6; By matrix-style a plurality of led light sources 3 are set on the LED lamp plate 5, luminous intensity distribution is reasonable, uses more a spot of led light source 3 just can reach higher brightness; Thereby realize energy-saving and environmental protection and the purpose that improves lighting quality, driving power 4 is fixed on reflection shield 11 rear ends.Diffuser plate 6 increases the lighting angle of led light source 3, and printing opacity is even, and luminous intensity distribution is reasonable.
Sensing module 2 is arranged on reflection shield 11 middle parts, and sensing is accurate.Reflection shield 11 is bucket-shaped structure, improves lighting angle of the present invention.The inner surface of reflection shield 11 is provided with reflector layer, can increase reflecting effect.LED lamp plate 5 closely contacts with heat dissipating housing 12 and is connected, and area of dissipation has just expanded on the whole lamp body 1 like this, forms all-in-one-piece radiator structure; Increase area of dissipation; And heat dissipating housing 12 is the material of good heat conductivity, has better heat dispersion, the heat in the time of can in time distributing led light source 3 work; Thereby solved the difficult problem of great power LED cooling, improved luminous efficiency and the useful life of LED.
